Pretty much. I'm sure they've been working the server changes gradually, as way back in December they appointed someone (Can't remember name off the top of my head) specifically to deal with the server issues. However we are not starting to see the benefits of that work until now, in the battle system. As they make other changes to "important" things like battle system that require more server changes, I think we'll eventually reach a critical point where they'll be able to knock out things like /l1 /l2 talk, remote LS controls, mailbox, etc., in quick order because the majority of the back end will already be fixed.
